Tips for finding research topics or gaps quickly?

I’m a 4th year student pursuing my undergrad in commerce from Delhi University, India. I need to write a research paper as part of my program and have to finalise a topic in the next 2–3 days. My area of interest is financial inclusion but I’m struggling with how to narrow it down to a good research topic quickly. Do I have to read through a lot of existing research papers to identify gaps or are there more efficient ways to find a feasible topic? Any advice or strategies would be really helpful.

P.S. - I have to complete this research paper in about 6 months or so and I’d prefer a topic where I can rely on secondary data or primary data which I can easily collect form my batchmates. Any advice or strategies would be really helpful.
